I see the crash happening on the following kernels, so that seems
unlikely:

But thank you for the info, at least we can rule out a change in mesa
having broken things. We can perhaps close this bug then, at least until
I can investigate further what the root cause is.

Title:
[radeon] Chrome crashes in RADV 21.2.6 on Ubuntu 20.04.6
Status in mesa package in Ubuntu:
New
Bug description:
Hi, Chrome/ANGLE developer here.
We've started observing crashes on Ubuntu 20.04.6 in
libvulkan_radeon.so since December 5, 2023. So far, all crashes seem
to come from that specific Ubuntu version, and with RADV 21.2.6.
Speaking with a mesa RADV developer, that version hasn't had an update
since Nov 2021.
While there's always a chance that an update in ANGLE has hit a bug,
the timing does not work out (Chrome Beta has been fine since November
1, but the crashes started happening on Dec 5).
Has there been an update to this driver around Dec 5, 2023 in Ubuntu
specifically? I'm wondering if there has been a (security) update done
by the Ubuntu team that upstream mesa may not be aware of. I can't
find a public history of updates to ubuntu packages (with associated
dates), is it possible to look at / provide that info and see what
happened around Dec 5?
Additional context is crbug.com/1508940, but I'm afraid not much is
visible publicly. The crash stack is nonsense unfortunately.
Cheers
